PANDEELS SM550 Universal 120V Bathroom Exhaust Fan Motor Kit — 50 CFM, Quiet Replacement with Blower Wheel

PANDEELS SM550 is a universal 120V bathroom exhaust fan motor kit designed to replace common small fan motors and restore quiet, efficient ventilation.

When a bathroom fan grows noisy, stops spinning, or delivers weak airflow, swapping the motor is an economical way to regain performance without replacing the entire fixture. The PANDEELS Universal Bathroom Fan Motor Kit (SM550) includes a blower wheel and plug-ready wiring, fits many common replacement numbers, and is sized for compact household exhaust fans that need about 50 CFM of airflow. This product listing explains fit, installation basics, mounting dimensions, and practical benefits so you can confirm compatibility before purchase.

How do I know if the SM550 will fit my exhaust fan?

Check your existing motor’s key measurements and model references. The SM550 is built to match common compact fan motors and lists several cross-reference numbers and compatible brands to simplify verification.

• Blower wheel diameter: 4 1/2" and height 1"
• Shaft size: approx. 3/16" diameter by 1 3/4" length
• Mounting studs spaced ~1 7/8" on center with 5/8" coil stack
• Matches replacement models: EM550, 65100, C65878, VFM100 and others

What performance can I expect from this replacement motor?

The SM550 runs on standard household power and is tuned for small bathroom exhaust fans. It delivers modest airflow suitable for single-bathroom ventilation and is made for reliable rotation at higher RPMs.

• Voltage/frequency: 120V, 60Hz
• Current draw: 0.29A for low power consumption
• Speed: approx. 3000 RPM for consistent fan rotation
• Airflow rating: roughly 50 CFM (suitable for compact fans)

How difficult is installation and what tools will I need?

Installation is straightforward for anyone comfortable with basic hand tools and safety precautions. The kit is plug-ready and replaces the motor using the original mounting bracket so most DIYers can complete the swap quickly.

• Turn off circuit power before beginning work
• Tools commonly required: screwdriver, pliers, nut driver, possibly a wrench
• Remove old motor from bracket and transfer or align the bracket to new motor
• 6" wire length with two plugs simplifies reconnection in many setups

Which brands and original part numbers does the SM550 replace?

The SM550 is designed as a universal replacement and cross-references many widely used OEM numbers and fan makers. This helps you identify compatibility without guessing from vague descriptions.

• Replacement models include EM550, EM750, 65100, C65878, VFM100, E498-1
• Compatible with brands like Nu-tone, B-roan, Gulf Motors, Uppco, Ventorola, Sears, Dayton

Who is this for? Homeowners, landlords, and handypersons who want a cost-effective way to restore a small bathroom fan’s function will benefit from the PANDEELS SM550 kit. It’s best for installations where the fan requires a compact 4 1/2" blower, a short shaft, and standard 120V power. If your motor matches the listed dimensions or cross-reference numbers, this kit offers a practical replacement with plug-ready wiring and customer support to help with fit questions.
